HONG KONG.- Bonhams announces its much-anticipated auction of Snuff Bottles from the Mary and George Bloch Collection Part IV, to be held in Hong Kong on November 28, 2011 at the Island Shangri-la Hotel. Following extraordinary results achieved by Bonhams for Parts I, II and III of the collection, in which every snuff bottle from the collection was sold, with world records broken in eleven different categories, Part IV is eagerly awaited by collectors. The sale features a total of 170 snuff bottles with an overall estimate of HK$21,000,000 – 38,000,000.
